What happens when zinc reacts with sulphuric acid class 10?

when zinc reacts with dilute sulphuric acid, Zinc sulphate is formed & Hydrogen gas is evolved. Zn (s) + H 2 SO 4 (g) → ZnSO 4 (s) + H 2 (Zinc) (dil. Its formula is H₂SO₄. Zinc metal gives hydrogen gas when it is treated with dilute sulphuric acid.

What is the chemical equation when zinc reacts with dilute sulphuric acid?

Balanced equation for the reaction between zinc and dilute sulphuric acid is: A) Zn+H2SO4(dil)→ZnSO4+2H2.

What happen when metal react with sulphuric acid?

Dilute sulfuric acid reacts with metals higher than hydrogen in the reactivity series to form sulfate salts and hydrogen gas.

What type of reaction is zinc and sulfuric acid?

Reaction of Zinc with Dilute Sulphuric Acid Zinc reacts with dilute sulphuric acid to form zinc sulphate and hydrogen gas is evolved. This is a single displacement reaction of a non-metal by a metal.

Is Zn H2SO4 exothermic?

Reaction between zinc with sulphuric acid is slightly exothermic.

What happen when dilute sulphuric acid is added to zinc powder?

When dilute sulphuric acid is poured on zinc granules, then zinc being more reactive than hydrogen displaces it from the acid and forms zinc sulphate and hydrogen gas. Hydrogen is a combustible gas and burns with a popping sound. This can be observed when a match stick which is burnt is bought ear to the test tube.

Do all metals react with acid?

Acids react with most metals and, when they do, a salt is produced. It doesn’t matter which metal or which acid is used, if there is a reaction we always get hydrogen gas as well as the salt. However, how quickly the reaction goes depends on the metal used and how high up in the reactivity series it is.

What kind of reaction is acid metal?

Revision Questions

Type of chemical reaction	General word equation
acids with metal oxides	acid + metal oxide → salt + water
acids with metal hydroxides	acid + metal hydroxide → salt + water
acids with metal carbonates	acid + metal carbonate → salt + carbon dioxide + water
acids with metals	acid + metal → salt + hydrogen gas

Why sulphuric acid reacts with zinc?

Reaction of Zinc with Dilute Sulphuric Acid Zinc is more reactive than hydrogen and it displaces hydrogen from dilute acids. Zinc reacts with dilute sulphuric acid to form zinc sulphate and hydrogen gas is evolved. This is a single displacement reaction of a non-metal by a metal.

Does zinc dissolve in sulfuric acid?

Zinc metal dissolves slowly in dilute sulphuric acid to form solutions containing the aquated Zn(II) ion together with hydrogen gas, H2.

What happens when zinc is mixed with sulphuric acid?

The gas produced in the reaction is hydrogen. Zinc reacts with dilute sulphuric acid to produce hydrogen gas (H 2) and zinc sulphate. . This is an example of displacement reaction of a non-metal by a metal. 2. Zinc is more reactive than hydrogen. .

What are the chemical reactions of zinc metal?

Chemical reactions. Zinc metal dissolves slowly in dilute sulphuric acid to form Zn(II) ions and hydrogen, H 2. In aqueous solution the Zn(II) ion is present as the complex ion [Zn(H 2O) 6] 2+.

What are the effects of sulfuric acid on metal?

Diluted sulfuric acid (H 2 SO 4) and magnesium, for example, will react vigorously: Mg + H 2 SO 4 -> MgSO 4 + H 2. In practice, not all of these metals will react with sulfuric acid under normal circumstances. Although the pure metals will react, some elements, when exposed to air, quickly acquire a layer of oxide.

How does zinc react with oxygen in aqueous solution?

Zinc metal dissolves slowly in dilute sulphuric acid to form Zn (II) ions and hydrogen, H 2. In aqueous solution the Zn (II) ion is present as the complex ion [Zn (H 2 O) 6] 2+. Zinc reacts with oxygen in moist air. The metal burns in air to form zinc (II) oxide, a material that goes from white to yellow on prolonged heating.
